BIOBLACK Mobile Application User Guide

18 June 2026

Introduction and Overview

This system has been developed with a citizen science approach to encourage public participation in marine research and to increase awareness regarding Black Sea biodiversity. Users can contribute data by sharing their observations of marine life along with location information via the mobile application or website. To ensure scientific accuracy, all submitted data is reviewed and approved by experts before being published.

Installation

To install the mobile application on your device, search for the Bioblack app in the Play Store or App Store, then download and install it.

Welcome Screen

Locate and open the installed application on your home screen. The welcome screen (as seen in Figure 1) directs users to the login, registration, and language selection processes. To navigate the app without registering, the "Continue Without Registering" button at the bottom of the screen allows the app to be used in Guest Mode.
